iMesh::get3DFaceVertexIndexInMesh()

Description

Helper function providing access to the geometry of the underlying 3D mesh.

Syntax

tSigned32 get3DFaceVertexIndexInMesh(tSigned32 faceIndex, tSigned32 vertexIndexInFace) const;

Parameters

	faceIndex		The (zero based) index of the face in which to look up vertex geometry. (Must be positive and less than the value returned by iMesh::getNumberOf3DFaces().)
	vertexIndexInFace		Value must be 0, 1 or 2.

Return Value

Returns an index for this vertex, within the mesh.

Remarks

This method can be useful in certain specific cases where code reproducing the mesh structure of the ground represented by this iMesh object needs to be implemented outside the API.
One specific example of this is when writing code to wrap an iMesh object for the iFaceVertexMesh interface.
